sex ratio

Climate change represents a real threat to the environment and, according to a study published on April 9 in the Proceedings of the Royal Society B, it has already made its first victim, namely the coqui frog, that could become extinct if the female animals do not alter their hearing in order to pick up the males’ changed chirps.

Rafael Joglar, professor of biology at the University of Puerto Rico added that, as temperatures rise, the fungus Batrachochytrium dendrobatidis causes fatal skin infections which could kill one of the territory’s symbols, namely the small brown tree frogs.The Guardian, 10 Apr 2014

A recent study published in the prestigious scientific journal Nature reveals a new way that lizards might be affected by the higher temperatures (on average) that our planet has been doing through.

The researchers studied a population of Bearded Dragon lizards in Australia, an animal who’s sex is usually determined by a combination of genetic and environmental factors, and found that the heat was actually making eggs with male chromosomes turn out female after a climate sex-change, so to speak.Tree Hugger, 2 Jul 2015

Even though sea turtles tend to live in warmer waters, the climate changes do affect their natural habitat. The climate is also believed to affect the sex of the younglings.

So if they temperatures continue to significantly increase it is believed that there will be many more females than males in the world. Yet these males likely won’t be able to keep up with the need of the females when it comes to reproduction.Sea Turtle World, undated
